Today is Thursday, January 19. My iphone would not play any audio unless it was previously saved to the phone. Any streaming audio or video (youtube, apple music, etc) would have a nice glitchy static noise approximately every second and if there was video, it would not be in sync (also wouls not be N'SYNC, but that is not a bug).
So, now that Apple's phone is the new Windows Computer, I rebooted it.

When it powered back up, an iMessage my wife sent me on January 9th finally arrived. It appeared as the newest message even though the date and time were correctly listed.
